Gee. Who warned again & again about the damn barcodes printed on machine marked paper ballots (as opposed to pen & paper). I did! And, of course, @MarilynRMarks1, @jhalderm, @rad_atl, @SEGreenhalgh, @TheBradBlog, etc. (PS. ES&S uses them too.) #BanBarcodeVoting 1/ 
In fact, I believe I published the first article warning about barcodes on ballots. 2/ #BanBarcodeVoting
I published it on Medium first. 3/ link.medium.com/cIjuatIiuqb
😳ES&S’s ExpressVote voting system reportedly has an integrated zebra technologies barcode reader whose “operation can be modified by scanning configuration barcodes,” which can “reconfigure which types of barcodes the scanner reads,” & “how it reads...&..processes them.” 1/
2/ “They could cause the barcode scanner to stop tabulating ExpressVote barcodes or to tabulate them incorrectly. They can even be used to allow sending unintended data & keyboard commands to the voting system.”
3/ “A set of carefully constructed keyboard commands could be used to manipulate the voting system software.”
